Electric vehicle standby declaration method and system based on multi-scene risk prevention and control

The invention discloses an electric vehicle standby declaration method and system based on multi-scene risk prevention and control, and the method comprises the steps: proposing an optimization target that an electric vehicle participates in a day-ahead electric energy market and a day-ahead standby market at the same time, the standby market income comprises day-ahead standby capacity income and intra-day standby power consumption income, and the electric vehicle participates in standby capacity optimal configuration of the day-ahead electric energy market and the day-ahead standby market at the same time in the day. According to the method, various constraint conditions in an actual application scene are determined; the risk that a plurality of standby vacancy events occur within a day is considered in an electricity market environment; the possibility that the spare capacity of the electric vehicle is called for multiple times in any time period in the day is considered; through multi-scene risk prevention
